Sustainability

We believe that Aleris, and aluminum, play an important role in advancing the sustainability of the metals sector and improving the sustainability performance of the customers we serve. For many years, we have worked to reduce our operational footprint, while increasing use of recycled content in our products. In 2014, we further evolved our program, by taking the next step in producing our first sustainability report. Since then, our latest report can be found below.

When we began developing our strategy several years ago, we started by engaging over 40 internal and external stakeholders, including functional leaders, customers, suppliers, investors and industry organizations, to better understand the economic, social and environmental issues driving sustainability across our entire value chain.

We used these insights to conduct our first materiality assessment, ranking each issue according to its importance to stakeholders and our business strategy. The assessment identified 21 material issues and helped guide development of our first set of sustainability goals, which are highlighted throughout our sustainability report.

We use our investor website (investor.aleris.com) as a channel of distribution of Company information. The information we post through this channel may be deemed material. Accordingly, investors should monitor this channel, in addition to following our press releases, Securities and Exchange Commission ("SEC") filings, and public conference calls and webcasts. The content of our website is not, however, a part of our SEC filings, public conference calls and webcasts.
